> It's a bit tricky to get beavers to build dams where humans want them, but this story is about beavers that did exactly that. It doesn't scale, but it worked here. No irony needed. It worked here by luck, indeed. The irony comes in when people share this story as some kind of gotcha against government spending and regulations regarding projects like this - as if "Haha, see silly government, all you need is some beavers to build dams" is a logical position to take. > Once built, a good dam is a good dam. Well... no, because such things need maintenance. Beavers, being animals, don't really have a concept of "round the clock maintenance" or "replacing maintenance workers". Again I ask, what happens when those beavers die? > Beavers don't build bad dams. Beavers are better dam maintainers than humans are. Citation needed. > More reliable and less expensive. I'll grant you that it's less expensive. That's not inherently a good thing, if you're sacrificing quality/safety/etc
